T 0 all whom it may cancer 1t. J

Be it lniown that we, .DANA l'I. BENJABIIN and ltliuiL u. Cmuumn, citizens of the United States. residing at Cleveland l leights and Cincinnati, respectively, in the counties of Cuyahona and l-lamilton, respectivelj Q and State 01' (lino, have invented certainnew and useful Improvements in GarmentjPresses, of.

which. the l ollowinp; is a specification.

This invention relates to pressing machines such as are used for pressing gal; ments or other articles 03" wearing apparel. or "for pressing fabrics 01" any kind. The invention has more particular relation to what are known as power presses andis an improvement upon the machine showindescribedand claimed the patent of William E. Andree for garment press No. l. 368,68 l, of February 15, 1921.

In this type of power press the two relativcly movable pressing: men'ibers are broue 11' into .l airly close neighboring relation either manually, *by pulling" down upon 'the' head. or by pressing down upon the usual. foot pedal. The power mechanism of-the press then produces furtherrelative'movcnient of the pressii'ip; membersto press the fabric or garment therebetween under heavy pressure. v 1 J! i J. .L.

lhe object or the present. invention is to provide an improved. pressing machine of this kind having power mechanism capable of manual control, thereby enabling it to be thrown into operation at the will of the operator. the control mechanism however being equipped with suitable safety devices to prevent actuation'of the power mechanism the manual control unless the pressi' members are in such close neighboring relation that it is impossihlefor the of the operator tolie thereliietween and hence be subject to injury.

A further object of the invention is to provide control devices of the character described which enable the two pressing mein-- hers to be relatively moved toward and from each other manually or by actuation. of the ioottreadle as often as may be desired, without tripping oil or starting the power mechanism.

further object of the invention is to provide a pressing" machine o'f this kind whose control; devices enable the operator Serial No. 234,258.

toset the same so that the act of manually or I otherwise bringing the pressing inembers into close neighboring relation so close that the fingers cannot be between said n1e1nberswill trip oil the power mechanism and cause the press to perform its regular series of functions and operations. Further objects of the invention are in part obvious and in part will appear more in detail hereinafter.

In the dra rings. which represent one embodiment of the invention, Fig. 1 is a side elevation of the left hand side of a press embodying the invention. the press being shown in open position ready for actuation by the operator; Fig. 2 a right side view of said press, the press being shown in closed position; Fig. 3 is a plan view; Fig. 4 is a detail sectional elevation on the line 44, Fig. 1; Fig. 5 is an enlarged side detail view oi the vacuum valve operating devices; Fig. 5 detail plan view of a lever; 6 is detail sectional elevation of one of the con trolling; switches a portion of the casingwall thereof beingbroken out to expose interior parts; Fig. 7 is an end view from the ri ht in 6. a portion of the casing wall being broken out to expose i uterior parts; Fig. 8 is a'detail elevation. partly broken out and in section, illustrating a plunger switch; 9 is a similar view of the rentingtiming switch; Fig. 10 an end elevation thereof; Fig. 1] is a diagrammatic View illustrating the electrical connections from the motor to the various control switches, the positions of the parts corresponding to the open position of the machine illustrated in Fi 1 Fig. 12 is a similar view of the parts while the power mechanism is producing heavy final pressure between the pressing members; Fig. 13 is a similar view of the parts when the machine has come to rest atter the application of heavy pressure; Fig. 14 is a similar view illustrating the positions of the parts when the motor has again been started to release'the press; and Fig. 15 illustrates the final portion of the opening movement just prior to the position shown in 11.

The general construction of the machine and its operating mechanism are not essential and may be chosen according to the lessee? requirements for any desired class of Work. The particular machine shown in the ings is in many respects similar to tne machine of the prior Andree patent above ferred to to Which reference may be had "for a more complete description of any portion of the mechanism not here described. A machine suitable for the purp oit this application, llOWQVI-f, comprises a suitable frame 1 carrying a stationary lower pressing member or buck 2 and provided with an upwardly extending support 3 for pivoted arm or lever 4 carrying a cooperating upper pressing member or head 5 adaptedby swinging movement of saic arm to be brought into co-cperating pressing relation with the buck 2. The buck may of hollow form having an inner chamber 7 to which steam is supplied for heating the buck in the usual manner, and, as shown in said Andree patent, may be provided With a steam chamber 8 arranged to discharge steam for moistening purooses through the perforations 9 in the face oil the buck, said steam coming from the heating chamber by Way of a valve 10 controlled by the valve rod 11 actuated by the steam] treadle l2. Said steaming chamber may also ci'u'ninunicate by Way of a valve with a pipe or conduit 14 leading to a suitable source oz"? suction or vacuum, such as the met 4 fan or centrifugal pump 1t 16 repi seats the rod by which the valve 13 is actuated to connect the chamber 8 to the source of suction, When desired or necessary. The no tuating means for said vacuum valve rod will be later described.

The head 5 is also heatech having an inner chamber through which steam is circulated by the usual pipes 17. Said head may also be provided with suitable means for supplying steam to the garment or fabric on the lower buck. Said means may be of substantially the same form shown descril and claimed in a prior patent oi William l5. Andree for garment presses granted July 29, 1919', No. 1311 151, and as shown co prises a long conduit or channel. 18 e2-;teuding along the front edge of the head and from slots or openings in which steam is discharged in the form of'a cloud traveling across or along the face of the head. Steam is supplied to said conduit from the chaos her in the head by Way of a pipe or conduit 19 in Which is a valve 20 norn'ially held closed bya suitable spring and capable oi being opened at will be depressing the handle 21.

22 indicatesa handle carried by the arm 4 for manually moving the arm and head toward or'from the buclr, the countenweight 23 serving to partially balance the load. The head may also be actuated by pressure applied to the foot treadle 24:, which is con-- nected by a link 25 to one arm of an oscildri i lating lever 26 the other arm of 1 connected by a linl; 2'? t the pivotal sin 22 lJO'S'JWQG 'tWO toggle members 29, 30, one of which, such as n'icinber i oral adjustable as to r. i of a pair of springs the press open.

having slidin Lie treadlc m. a pin to a sleeve inov nent a rod 50 connected at its .1 end to an arm 51 pivoted at to the no and pressed by a I ainst the cam J 4 Between the s eve 49 and a cell r 54; 1S a compression spring 55, while on the other side of the sleeve l9 the rod is provided with adjustable abutment nuts 56.

Upon first closing the press the roller 2%1 engages the arm i? aginst the action of spring and moves down past the same, said arm then adv cing to position slightly above the roller. Then operation of the gear 39 by the motor will cause cam .i-"l to engage lever 51 and move the lock arm 4'7 to the position shown in and thereby lock the press closed. It cannot be released until the motor is again operated through the second. half of its cycle, which operation moves the cam 44- away from lever 51 and allows the spring 53 to move back the loci:- ing arm 47 and release the roller 2%.

If the press is to be power actuated, it is not necessary for the operator to depress the treadle to its full extent so as to cause the toggles to move center and become lOClk'fld, but the locking of the treadle may be accomplished solely by the treadle lock 45?. However, when the press is to be used as a foot power press, either continually or merely occasionally tor a sin le foot operation, an additional downward movement of the main treadle, usi'.' ly requiring pro nounced toot pressure for the purpose. moves said main treadle to its full :atent and causes the toggles to move ightly pa. t straightened position to perform the loclc ing function. In the latter case the toggles are broken by ordinary actuation of the re lease treadle, whereas in the "former case release or opening operation of the power mechanism moves back the loci: 4'1 and the press is immediately opened by the ellect oi the springs 81 and counter-we t 23, because the toggles are not fully straightened and the meclanisin is not otherwi e locked.

The actuating mechanism for the vacuum valve is so arranged as to enable the vacuum to be rendered eii'ective either automatically by the operating movement of the press when the press is power actuated or by operation of the release treadle when the press is operated manually without the motor: lt

will be understood of course that the motor 5? (Fig. 11), for actuating the fan or pi p 15 is in a branch circuit 58 connected through a suitable switch 59 to the power leads 60, and when the vacuum is to be utilized the s vitch 59 is turned to a position to cause operation of the motor. ln other words the fan is constantly operative and the valve 13 actuated at the proper time to cause the vacuum produced by the fan to become ellcctive in. the buclc chamber 8. Refer to Fig. the machine is provided with suitable bearings to carry a transversely extendin shaft 61 with which turns an arm 62 having a yoke portion embracing the stem 16 and an arm 63 connected by a link 6%- to an arm 65 connected to turn with and to be actuated by the release treadle s5. Directly above the yoke portion of 62 is an arm 66 having a yoke beneath a collar 67 on the valve stem and mounted to turn on the shaft 61 with a cam arm 68 the memhers 66 and 68 operating as one piece. Cain arm 68 co-operates with a pin 69 on the lever 26.

When the press is power actuated the release treadle is not utilized and is held in the position shown 1 by the spring 70. The swinging members 66, 68 are however actuated by the pin 69 which when the press opens engages the arm 68 and through member 66 lifts the valve 13 and applies the vacuum. The vacuum remains effective in the chamber 8 until the press is closed to move the pin 69 away from lever 68. When the press is not power actuated the vacuum is rendered effective by depressing the release treadle, which causes the arm 65?, to lift the arm 66 and thereby open the vacuum valve.

Referring now to Figs. 11 to 15 the current lead wires 60 pass tl'irough a suitable switch 71, one of said lead wires running to tie power motor 13 and thence to the center contact of a tumbler switch 72 shown in Figs. 6 and 7. From the two end contacts of this tumbler switch lead wires 73 and 74: extend to binding posts 130, 131 on the lower and upper segments of a rotating distributing or timing switch 5, snown in Figs. 9 and 10 and from the center contact of the timing switch lead wire 76 extends to the switch '71. ln one of the leads "from the tumbler switch to the timing switch, such as lead 7%, is a phmger switch 77. lhe several switches 72, an 77 will first be described.

Tumbler switch comprises an insulating block 78 on which are mounted two end contacts 79 and 80. connected respectively to the'binding posts 73, We. The center contact to which the lead from the motor is connected, is a post 81 on which turns an upwardly extending arm 82 carrying the spring pressed contact blade 88, said arm having a rear post connected by a tension spring 84 to a sliding rod 85, all parts being suitably insulated. Rod 85, 1, extends outwardly from the front of the switch casing and is connected by a linlr 36 to on 8'? on the shaft or tne opera ng l which at its opposite or. carri This arrangement produces a "g and break. By moving the lever 88 in one direction or the other the rod is moved longitudinally in the switch or and carries the lower end of the spring 84: past the pivot of the swinging arm 82, which 'tjafil'Q- fore turns over with a quick snapping movement to break one contact and make the other, thereby changing the connection of the motor to one or the other the leads 73, 74. Any other form of switch for shift ing these contacts would however answer the purposes.

The plunger switch 77 is illustrated in Fig. 8 and comprises an insulating bloclr 89 carrying two contacts 90, one connected to the lead 74 and the other to one of the seg ments of the switch 75. Between he two contacts 90 is located a sliding fibre rod 91 carrying a conducting rin contact 92. This rod projects downwardly tom the bottom of the switch casing and within the said casing carries a collar 93 above which is a compression spring 9d whose upper end ongages a washer 95 seated against a wall of the casing. As shown in 8 the spring 94 normally holds the switch open. The lower end of the rod 91 has a nut or bolt 96 adjustably connected thereto, and lies in position tobe actuated by an arm 97 mounted to turn with an arm 98, the latter arm having an abutment 99 lying in the path or movement of a too 100 of the swinging lever 27. l/Vhen the press is closed manually, so as to bring the head and buck into close neighboring relation-so close in fact that the fingers could not be between them the toe 100 actuates lever 98 and closes the plunger switch. As will hereinafter appear this switch must be closed before the power motor can be operatively connected to its source of current, as a consequence of which it is impossible to produce the final heavy pressure with the power motor unless the press has first been nearly closed manually. In any other position of the head, actuation of the manually controlled tumbler switch 72 will have no effect uponthe machine.

The rotating timing switch may be of any suitable form. As illustrated it comprises a suitable casin 101 provided with radially and outwardly extending car having circum'ferentially extending slot 121 through which a bolt 122 is screwed into the machine frame. The elongated slot 121- permits slight adjustment of the casing 101 around the axis of the shaft 40 at the center or" said casing, the adjustability of said casing being for a purpose which will later appear.

again connects the motor its source through segment the tumbler switch and the lower of the timing switch. The motor thereupon begins to rotate and turns the cam shaft through the second half of: its cycle, as shown in Fig, 15, the parts finally reaching the position shown in Fig. 11. 'lhe :hrst effect of the motor is to break the third. tog 'le, and as soon as the car 44. leaves the lever 51 the lock 4-? moves bail: a. releases the roller 2r, a result of the springs 31 fully open the press. ap-

During the first closing movement oi the press the pin 69 moves away from the lever 68, so that the vacuum valve closes. Till the vacuum valve is closed and up to the time the head and buck are in "Full. coutart steam can be appl ed to the garment either by actuation of the steaming 'treadle 12 to discharge steam from. the buck, or by actr: ation of the lever 21 to discharge stean'i from the head.

other words,sai jl motoroperates so l( as the rotating shoe 10? is in contact either of the segments 102, 103. and Hill motor stops operating (excepi as: to roasting hereinafter referred to) when said shoe drops oil frourthe end of one ou said segments and cup; ges the other. The shoe 10'? rotates with and always has a ned time relation with the shaft 40, the circuruien ential position of which determines the position of the head. By circumterentially adjusting the two insulating blocks 128, 124 in the casing, nicety and accuracy as to starting and stopoi of the o citing mechanism ii i may be secured and the two halves of the cycle maybe terminated at the most eflicient olnts. For example, segment 102 is the egment along which the. shoe travels whlle press re is being applied. by the motor. segment is made longer than segment 103 ."iGfillilSQ the load on the motor ncreases as he shoe 107 reaches the end of the segment, as a result of whic i the motor cannot coast under load. By circumferentially adjusting segment 102, its far end can be made to assume a position in which the maximun'i pressure has been applied to the head, and with such adjustment the press will stopwith the maximum pressure applied. 7 Segment 103 is shorter than segment 102 because the shoe 107 is travelling over segment 103 while power pressure is being relieved and the load is decreasing. As a result, the motor has a tendency to coast at the end of this half-cycle. This segment however can also be adjusted so as to compensate for any coasting tendency and insure the press coming to rest with the head fully open. 7

The above two adjustments of the blocks 123, 12 1 enable the starting and stopping points to be individually determined for the two halves of the cycle. For additional adjustment and to also simultaneously adjust both segments, the casing 101 can be circumferentially adjusted relative to the frame, which has the eliect of circumferentially adjusting both segments and changing the time of starting and stopping of both halves of the cycle as already determined by the positions of the segments in the casing, with respect to the position of the head atfull open or full closed position.

lit is, of course, obvious that the insulating block 105, which carries the rotating shoe 107, is capable of rotatable adjustment on the shaft 40 to time it with relation to be head, and said block can be secured to the shaft in any of its adjusted positions by the set screws 1A0.

The machine described materially reduces the labor of the operator and while giving him full manual control. over the press prevents him from putting into efiect its power features except when it is safe to do so.
